Pollination is the process where pollen, produced by the male part of a flower (the anther), is transferred to the female part (the stigma), enabling fertilization and seed production

Pollination syndromes= suites of flower traits that have evolved in response to natural selection imposed by different pollen vectors. Pollen vector can be abiotic (wind and water) or biotic through different animals (pollinator-mediated selection)
Gymnosperms rely on inefficient abiotic wind pollination
Angiosperms (flowering plants) first appeared ~140 million years ago (Cretaceous)
Flies: Mimic bees/wasps, short or medium proboscis, often visit open flowers; limited body hair (less efficient pollinators)
Butterflies/Moths: Long, coiled proboscis suited for deep tubular flowers; butterflies are diurnal and visual, moths are nocturnal and rely on scent
Beetles: “Mess and Soil” pollinators: eat flower parts and leave behind poop on flowers. Damage flowers but still transfer pollen
Hummingbirds: Long, slender beaks and brush-tipped tongues to reach deep nectar tubes; hovering flight minimizes flower damage
Bats: Strong sense of smell, adapted for nocturnal feeding; furry bodies collect and spread pollen efficiently
